Question

A faraway planet is populated by creatures called Jolos. All Jolos are either green or purple and either one-headed or two-headed. Balan, who lives on this planet, does a survey and finds that her colony of 500 contains 100 green, one-headed Jolos; 125 purple, two-headed Jolos; and 270 one headed-jolos.How many green Jolos are there in Balan's colony?A. 105B. 170C. 205D. 230

Answer 1

According to the table, there are 270 one-headed in total, and there are 500 Jolos, we just have to subtract to find the total of two-headed Jolos

`500-270=230`

There are 230 two-headed Jolos.

Now, we subtract the total of two-headed Jolos and the two-headed purple Jolos to find the total green.

`230-125=105`

There are 105 two-headed green Jolos.

At last, we have to sum the number of one-headed green Jolos and the two-headed green Jolos,

`100+105=205`

Hence, there are 205 green Jolos in total.
